how to read data from mifare card I'm using an ACS 1252U to read the tags, and I've tried manually iterating over some of the data to get a sense of what's on the tag, but I can't seem to figure out how to determine where the record begins and where it ends.

The MIFARE® Classic family is the most widely used contactless smart card ICs operating in the 13.56 MHz fre-quency range with read/write capability and ISO/IEC 14443 A compliance. Smart cards based on MIFARE® Classic ICs are a commonly known solution in various applications such as: •Access Control •Public Transportation So the read command gives you 4 blocks (4 bytes each) starting at a given block offset plus a status word for the read command (0x9000 for success). In your case you get: Read(4, 16): 0103A010 440311D1 010D5402 656E4843 9000. Read(5, 16): 440311D1 010D5402 656E4843 49443030 9000.
I'm using an ACS 1252U to read the tags, and I've tried manually iterating over some of the data to get a sense of what's on the tag, but I can't seem to figure out how to determine where the record begins and where it ends.Reading the UID. The steps required in reading the UID from a contactless card requires the following steps. 1. Get context handle (SCardEstablishContext) 2. Connect to the card on the reader (SCardConnect) 3. Send the Get Data Command using SCardTransmit. 1) is there a way to read data from all sectors (encrypted card) at once using "hf mf rdsc"? just like this picture below. If not, I hope this command will be implemented in the new Proxmark3 release: hf mf rdsc * * keys.dic (similar to hf mf chk) 2) there are 16 sectors a 4 blocks, total 64 blocks. each block has 16 hex a 2 bytes.
The specifics to read Mifare Ultralight cards are detailed in §4.3.3.a (at the time of this writing). Le must a multiple of 4. We want to read the whole memory, starting from page 4: this means we want to read 12 pages of 4 bytes, so 48 bytes (ie: 30 in hexadecimal).But if instead you wish to read, for example, a specific sector of a MIFARE card, then Read-a-Card can return that data, formatted according to your requirements, using a software plug-in. You can also optionally store access keys securely in hardware.
For some tags, you need to include the key to read data from a sector, aid, orpage. Select a tab to see the parameters that you need to specify to read data from MIFARE Classic, MIFARE DESFire, or MIFARE Ultralight. CRYPTO-1 uses two 48 bits-long keys on Mifare Classic cards to encrypt the data on its sectors. Each key can be configured to be used for reading or writing on a sector.
